Document Summary
The joints that are most stable have the least mobility. The joints that have the least mobility are the most stable. The joints that have the most mobility are the least stable. The joints that are the least stable have the most mobility. Conoid tubercle - near the acromial end. Costal tuberosity - near the sternal end. Scapular spine, supraspinous fossa, infraspinous fossa & acromion. 14 phalanges in each hand (labeled as proximal, middle, and distal) Pollex only has two phalanges (labeled as proximal and distal) Absorbing shocks and jolts as you walk, run, or jump. Flexion and extension at the shoulder joint. Adduction and abduction at the shoulder joint. Medial and lateral rotation at the shoulder joint. Muscle that inserts close to the joint. Muscle that inserts far away from the joint. Agonist - prime movers; perform an action. * when an agonist is active, the antagonist relaxes.
